Will Yesstyle actually cancel my order?

I’ve been using mostly Stylevana for the past years and never ever had trouble cancelling an order or even adding/removing items to my order, they always replied quickly and refunded me to my original payment method.

I placed an order on Yesstyle and forgot to add a product I needed quite urgently, so I emailed customer support thinking the issue would be resolved quickly like Stylvana does. I (stupidly, I know) then placed my order again including the product I had been missing (again, quite dumb, I know).

After googling around a bit I saw that yesstyle has this on their website: “Can I cancel items after I've placed an order? Once an order has been placed, we do not allow for order or item cancellation. We kindly suggest that you read the product information carefully before confirming your order.”

Have I messed up by thinking my order could actually be cancelled properly or will they actually do it? The order has not shipped yet but everything was shippable in 24h soooo I feel like they might not get to my e-mail in time. Tried the live chat option, but it never redirects me to an actual person :(
